A good palette is important. It can help the viewer understand what kind of theme, feeling, season, etc! Now of course, if you're making a specific season for the skin to be in, remember that bright greens, pinks, and yellows can go together. Summer means warm time. Whip up those reds oranges and yellows for a hot summer day! Autumn is when the heat stops, the world slows, and beautiful red orange and brown leaves fall. (Fall and summer are basically the same, but put some browns in there ;] ) Winter is the opposite of summer! Greens, blues, purples, galore! Now, away from seasons, onto how create a palette. Find the colours you want, make sure they have the right tone, brightness, etc. Then you can use a google doc, the skin's arm until you're finished, to keep the palette where you can easily access. Don't forget to keep the hex code on there if you're using paper or something like it!
